CARBlD-PACKAGE FOR ACETYLEN E-G EN ERATORS.

SPECIFICATION forming part of Letters Patent No. 673,435, dated May 7, 1901.

Application filed April 11, 1900. Serial No. 12,401. (No model.)

To all whom it may concern:

Be it known that I, WILLARD O. HUGHES, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Acetylene-Gas Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon,which form part of this specification.

The object of my present invention is to provide an improved charging-case and package for acetylene-gas machines and means for perforating or breaking the package after it has been introduced in the machine.

In the drawings, Figure 1 showsa vertical central section of the charging-case with a broken carbid package in position in the charging-case. Fig. 2 shows details of the package-perforating mechanism.

The charging-case, as shown,consists'of two hemispheres A and B. The part A is provided with an inwardly-projecting rib 1 adjacent to the line of separation, while the other hemisphere B is provided with spring hooks or catches 2, adapted to engage with the said inwardly-projecting rib 1 at any point and secure the two hemispheres to-' gether. Within the parts of the case there are provided shoulders or seats 3, adapted to receive the cylindrical package 4, containing the carbid. The package 4 is preferably of pasteboard which has been shellacked on the inner surface to make it air-tight and watertight. The package 4 also preferably contains a transverse perforated tube 4",centrally located and held between the heads of the package and closed at the ends by the heads of the package.

Each hemisphere of the charging-case is provided with a package perforating or puncturing mechanism formed as follows: There are provided projecting from the inner surface of the case posts or standards 5, which are adapted to receive and'provide guides or ways for the cylindrical body 6 of the perforator. The body 6 is a short tube and is provided at one end with projecting knives -or cutters 6*, formed into a point substaning movement of the. perforator.

tially as shown. At the base of the perforator-body 6 there are provided lugs 6 ,which occupy spaces between the posts or standards 5 and are adapted to come in contact with the ring 7, secured on the heads of the posts or standards 5, and limit the project- The perforator is actuated by a spiral spring 8, interposed between the internal flange in one end of the body of the perforator and the inner surface of the charging-case. For securing the perforator in retracted position there is provided a latch or catch 9, pivoted at one end in the perforator and having on the other a head adapted to engage with the shell of the charging-case, as shown on the left-hand side of Fig. 1. In order to guide the free end of the latch or catch 9 and prevent it becoming entangled with the spring 8, there is provided a short inwardly-projecting tube 10, having an internal diametersufficient to receive the head of the catch 9 and allow it to slide freely backward and forward in the tube. The charging-case is provided with openings, as a, which allow the water to enter the charging-case when the same is submerged and also permit the gases generated within the charging-case to escape therefrom.

The operation of the charging-case is substantially as follows: To separate the parts, one or both of the catches 36 are released by forcing a probe through the opening 11 into engagement with the shank of the catch, springing the same so that the hooked end is free from the flange 1. When this is done, the parts of the case maybe freely separated. When separated, the package puncturing or perforating devices may be forced into their retracted position-that is to say, from the position shown on the right of Fig. 1 to the position shown on the left of the same figure.

When the perforator is forced back, the headed end of the latch or catch 9 drops over the outside of the shell and secures the perforator against the tension of the spring 8. When the perforators have been retracted, the carbid-package 4 may beplaced in position within the charging-case and the parts placed together and secured by the catches 2. The perforating or puncturing devices are then released by theoperator moving the headed end of the catch so that the head coincides with the opening in the tube 10, and the perforators are then moved toward the package under the impulse of the spring. When in its dry state, the resistance of the package is sufficient to hold the perforators in check, with the points pressing on the sides or heads 4 of the package. When the charging-cases are submerged in the waters of the apparatus, the water quickly soaks the pasteboard of the package, softening the same, and the pressure of the spring 48 forces the points and body of the perforator through into the package. This allows the waters of the tank to have access to the carbid through the tubular body of the perforator and through the perforations of the perforated tube 4 of the carbid-package. The perforated cross-tube 4c of the carbid-package removes all danger of the perforators coming in contact with pieces of carbid when'entering or attempting to enter the package,.

which might be the case if the perforated tube 4 was not provided. The perforated tube 4 also permits the water to enter to the body of the carbid and the gases to freely pass out of the same. By using two perforators engaging at two points and simultaneously operating on the package the package is punctured at two points and the gas generated within the package is allowed to escape at one or the other of the punctures, while the inflow of water into the package is not prevented by the pressure of the gas at the other opening or puncture.

While I have shown and described a spherical charging-case and a cylindrical package, being, as I consider, the most suitable and convenient forms, still it is apparent that my invention is not limited or to be restricted to these particular forms.

What I claim as new, and desire to secure by Letters Patent, is

1. A charging-case for an acetylene-gas machine having means for holdinga carbid-package and two spring-pressed package perforators or breakers simultaneously operating on said package, substantially as set forth.

2. A charging-case foran acetylene-gas machine having means for holdinga carbid-package, a spring-pressed package perforator or breaker and a catch for securing the perforator or breaker, substantially as set forth.

3. The combination of, a charging-case for an acetylene-gas machine having means for holding a carbid-package and a perforator or breaker held in check by the dry package, substantially as set forth.

4. The combination of a spherical chargingcase having means for holding a carbid-package within the case, in wardly-operatin g package perforators or breakers and means for forcing the package perforator or breaker, substantially as set forth.

5. The combination in a carbid-charging case of the two shells adapted to be secured together, having means for holding acarbidpackage, a package perforator or breaker arranged Within the case and a spring interposed between the perforator and the casing to force the perforator against the package, substantially as set forth.

6. The combination with a charging-case of an in wardly-operating package-perforator, a spring for actuating the perforator, a headed latch or catch connected with the perforator, and an inwardly-projecting tube 10 secured to the charging-case,substantially as set forth.

In witness whereof I have affixed my signature, in presence of two witnesses, this 7th day of April, 1900.

WILLARD C. HUGHES.
